Eevee get darker shadows
So here is a quick try: First, deactivate the world in the Shader Editor, increase a bit the strength of the 2 suns to 2, as the shadows are a bit too dark and as you need to compensate a bit the removal of the world, create a point light in the middle of your room, disable its shadow option and give it a strength of 300 W. It may need a bit of tweakings but I think I'm not far from what you want?
Edit: also, maybe a Light Probe &gt; Irradiance Volume will improve the lighting, to be tested
